About

I’m Josué Santos, a fullstack software engineer with years of experience building high-complexity projects across both backend and frontend. Throughout my career, I have worked in sectors such as fintech, acquirer, card issuing, marketplace, and SaaS, always focused on code quality, scalability, and security.

I have solid experience in languages such as Clojure, Golang, and JavaScript, along with expertise in relational and non-relational databases, messaging systems, cloud computing (AWS), and modern practices like CI/CD, TDD, and clean architecture. My work ranges from developing fraud prevention systems and implementing protocols like ISO 8583 to creating complex integrations and regulatory solutions for the financial market.

My approach blends strategic technical vision with hands-on delivery, collaborating closely with multidisciplinary teams to design solutions that solve real problems and generate measurable business value.
